IMPROVEMENT IN PUMPS.

Specification forming part ol" Letters Patent No. 208,739, dated October8, 197s; application iiled arch ll, 1878.

To all whom it may concern:

Beit known that I, SAMUEL N. JONES, of the city of Rockford, in thecounty of Winnebago and State of Illinois, have invented a new anduseful Improvement in Pumps, of which the following is a specification:

This invention relates more particularly to that class of pumps employedto lift water from wells and cisterns, and for other similar purposes,and the improvement relates to the connection with the cylinder of thevalve-seat and the kind of valve employed.

The object of this invention is to produce a pump-cylinder valve-seatconnection and yoke adapted to employ a puppet-valve as the lower valvein such a manner as to produce a reliable and durable pump at a smallcost. To this end I have devised and constructed the parts representedin the accompanying drawings, in which-` Figure 1 is an isometricalrepresentation of the lower portion of a pump-cylinder and valve-seatconnect-ion, of which Fig. 2 is a "plan view, and Fig. 3 is a verticalcentral section on dotted line w. Fig. 4 is an isometrical view of thepuppet-valve.

In the figures, A represents the lower portion of a pump-cylinder of anyproper diameter and length, and is screw-threaded at its lower end, asat a.. 3 represents the lower valve-seat portion, the upper end of whichis of proper size, and is screw-threaded inside, as at b, to receive thescrew-threaded end of the cylinder. This portion B is centrally boredlengthwise, as at c, forming the induction-pipe, and its upper end formsthe valveseat d. Between the valve-seat el and the inside of thecylinder A the portion Bis provided with an annular groove, c, whichgives to the valve-seat d a raised form.

At Fig. 4 is represented a puppet-valve, having its lower portion f ofbayonet forln, and is fitted to play freely up and down in theiiuluction-bore c. A packing-disk, g, is secured to the upper end of thebayonet-formed portion, and is held in Vposition thereon by a metallicdisk, h, secured on its upper side by a screw passing through the diskand packing into the portion j'. This puppet-valve is placed in theinduction -bore with the packing resting on the valve-seat, to which itwill be held by the action of gravity on itself and on the column ofwater to be raised, and when acted upon by the lifting force of theplunger in the operation of raising water the valve will rise from, itsseat and permit the water to iiow upward through the openings betweenthe conA cave surface of the induction-bore and the concave surface ofthe bayonet-formed portion of the valve.

C is a yoke, constructed with a ring-base, y1', from which rises archedribs L', which span the central opening. The ring-base i of this yoke isof proper form and size to enter the annular groove c, and when in placethe arched ribs will limit the upward movement of the puppet-valve, asseen in dotted lines in Fig. 3.

E is a packing-ring, made of any proper inaterial, and is placed inposition above the ringbase of the yoke.

Nith these parts (vin, the puppet-valve, the yoke, and the packin g-ring) in place, the valveseat portion is then screwed in place on the lowerend of the cylinder, and when thus connected it is ready for use--acomplete lowervalve connection with the pump-cylinder--and, inconnection with the usual puppet-valve plunger or other suitable plungerand the usual connections of pipes, levers, yor other similar knownappliances, is a complete pump for practical use.

Instead of the base-ring of the yoke, the arched ribs may be providedwith outwardprojecting feet adapted to enter seats prepared for theirreception in the valve-seat portion, and held in place when the partsare connected.

I claim as my invention The combination, with thecylinder and removablevalve-seat portion, constructed with an annular groove surrounding thevalve-seat,
